SAPONIFICATION: TRIALS AND TRIBULATIONS. Conor Dowdle. The purpose of this experiment was to see if by creating crude soap and then neutralizing it, could this soap compare to a generic brand soap bought from stores. By applying the age old process of saponification, crude soap can be created. Using modern neutralization methods to this crude soap, soap comparable to store bought soap can be created. The reactions were carried out accurately and the soaps created were mostly neutralized through the saturated salt solution. For example, the most successful soap, made from lard, tested at a 7 on the Ph scale, proving it was completely neutralized, as was the store bought soap. This process is based off of the age-old creation of soap. By building on this process we have proven it is still feasible, and quite simple to make quality soap, not relying on commercial brands. Key Words: Saponification, Neutralization, Ph, Saturated.
Deacidifacation of High Free Fatty Acid Containing
Rice Bran Oil by Non-conventional Reesterification Process.
Response to Article:
The process of reesterification is a process that has been proven successful on FFA (Free Fatty Acid). When the rice bran oil was subjected to a change of process during saponification. FFA is usually removed as stock during this process, but this process attempts to create a more efficient process, with less oil loss during saponification. This experimental rice bran oil is subjected to this newly created process. This process is a change from the classic saponification process. Saponification has been around for thousands of years, and in the last few centuries chemistry ahs adapted this process for more commercial use. This is a prime example of new technology allowing more efficient reactions. The saponification reaction has been changed for the better; by using reesterification on this bran oil the process was refined. Many of the dehydrated castor oils and bran oils showed a drop in acid, this seems to be a success for the process; it has increased efficiency through advancements in chemistry.

Soap never hardened, never became a gel and the reaction was never complete.
